RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 790,803, dated May 23, 1905.

Application filed June 22,1904. Serial lio. 213,641.

HTo all whowt it may concern:

Be it known that I, JOHN L. POPE, a citizen of the United States, residing at Cleveland, in the county of'Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention relates to railway-ties; and it has for its object to provide a railwaytie which is indestructible.

To these ends my invention consists in the features, arrangements, and combinations hereinafter described and claimed, an em bodiment thereof being illustrated in the accompanying drawings, in Which- Fx re I xs a side elevation of a tie, showing tgz track-railsthereon. Fig. II is a crosssection of a tie. Fig. III is a longitudinal section of a portion of a tie, showing a sustaining-block. IV is a section of a modiiied form of t1e.`

The reference-letter a indicates a railwaytie composed of fibrous material bound into 4a mass With a Waterproof cement, formingl a hollow tube which is preferably of arectangular cross-section havi rounded corners, as shown in Fig. II. Ot er suitable forms of cross-sections may be emplo Ted, if desired, Ione of which is illustrated 1n IV. I prefer to form thefibrous material into sheets or to make a paper thereof and build up the tie of superimposed 'layers of such sheets or paper bound to ether by Water roof cement, as indicated in Figs. II an III, or the fibrous material and the cement may be made into a mass and then formed into the desired shape in molds. While Various kinds of fiber may be used for this pur ose, I consider asbestos fiber to be preferab e, and a bituminous substance, such as asphalt cement, is suitable for a binder.

In order to reduce the amount of material in the body of the tie, I prefer to incor crate therein sustaining-blocks b at the rai -bearing portions of the tie but it is racticable to make the shell of the tie of su cient thickness that. the blocks b ma f be dispensed with, For the said blocks b do not confine myself to the use of an special material nor to any particular lengt `or cross-section, as

they may be either solid or hoiicu, and a singie block extending under both rails may be used instead of two, as shown, but it is proferred to employ a wooden block or bloc-.lis cemented within the tio, so as to be integral therewith.

The track-rails c may be fastened to the tie in the usual or any suitable way.

Having now so fully described my invention that those skilled in the art to which it appertains can make and use it, either in thc form shown herein or under some modification thereof, what I claim as new, and desire to secure by Letters Patent, isM

l. A tubular railway-tic of fibrous waterproof material having substantially straight Walls and rounded corners, substantially as shown ands described.

2. A tubular railwaytie com nosed of the incor eration of fibrous materia and waterproo cement having sustaining-blocks incorporated in the rail-bearing portions thoroof, substantiallyT as set fortl y 3. A tubular railwaytie of fibrous niaterial and a Water )roof binder having straight Walls with roun ed corners, and sustainingblocks of suitable material incorporated in the rail-bearing portions thereof, substantially as set forth.

4. A tubular railway-tie of fibrous waterproof material having portions of its walls curved, substantiallyT as set forth.

5. A tubular railway-tie of fibrous water; proof material having portions of its walls curved, and sustaining-blocks incorporated in the rail-bearing portions thereof, substantiaiiy asset forth. A

6. A tubular railway-tie having walls of equal thickness composed of fibrous material in sheet form, said material being permeated with waterproof cement, substan tially as set forth.

7. A tubular railway-tie having walls of equal thickness composed of fibrous material in sheet form, said material being permeated with waterproof cement, and sustainingblocksincor orated in the rail-bearin portions thereo substantially as set forth 8. A railway-tie composed of Waterproof paper Wound into a tubular form and ceroo mented into a mass, substantially as set In testimony whereofIaHX my signature, forth. in the presence of two subscribing Wltnesses,

9. A railway-tie composed of Water roof at Cleveland, Ohio, this 21st day of June, 1o paper Wound into a tubular form an ee- 1904. 5 mented into a mass, and sustaining-blocks Witnesses: JOHN L. POPE.

incorporated in the rail-bearing portions JOHN T. SULLIVAN, thereof, substantially as set forth. EDWARD LINDSLEY.
